(2011), Singh E.A. (2012), Patil U.J. et al (2011) and Patil & Patil (2011).
Methodology for the assessment
The study was conducted during February, 2013. The important tree species were identified and the ones which were endemic to the area were identified with the help of the local people. Around 10 local people were interviewed informally regarding the local names of the species. Furthermore, the data regarding the ethno medical uses of the species was retrieved from similar works conducted in various regions of Western Ghats, mainly in the state of Maharashtra. The uses find similarity along the whole belt. Thus, information from different sources was used and then compiled together along with the data collected from the site.
